I have one ffmpeg command that merges 3 mp4 videos together and then another command that applies a watermark to the output video of the first command. The commands are:

Merge mp4 videos with blending them together

ffmpeg -y -threads 0  -i vid-1.mp4 -i vid-2.mp4 -i vid-3.mp4 -f lavfi -i color=black -filter_complex "[0:v]format=pix_fmts=yuva420p,fade=t=in:st=0:d=0.5:alpha=1,fade=t=out:st=5:d=0.5:alpha=1,setpts=PTS-STARTPTS[va0];[1:v]format=pix_fmts=yuva420p,fade=t=in:st=0:d=0.5:alpha=1,fade=t=out:st=5:d=0.5:alpha=1,setpts=PTS-STARTPTS+5/TB[va1];[2:v]format=pix_fmts=yuva420p,fade=t=in:st=0:d=0.5:alpha=1,fade=t=out:st=5:d=0.5:alpha=1,setpts=PTS-STARTPTS+10/TB[va2];[3:v]scale=1280x720,trim=duration=15[over0];[over0][va0]overlay[over1];[over1][va1]overlay[over2];[over2][va2]overlay=format=yuv420[outv]" -vcodec libx264 -map [outv] -s 1280x720 -aspect 16:9 -r 30 -crf 1 -preset ultrafast output.mp4

Output:

Is there anyway I can apply the watermark at the same time as blending the mp4's? I want to be able to do this in one command.

  • Remember to always include the complete console output with each command (or at least the first one in this case); you'll get answers faster and they will be more accurate. What's the reason for adding -threads 0 as an input option? Why use 1 as your crf value?
    – llogan

  • I will add the console output. But, this is meant to run concurrent alongside multiple processes and the threads are determined by how many processes are running so the cores are distributed evenly between the ffmpeg commands. I was only running one process for this so it is allocating all cores to the command. And I'm using "-crf 1" so the quality is as high as possible

  • -threads as an input option will only apply to decoding the input that follows it. As for encoding with libx264, -threads 0 is the default; 0 means "automatically choose the appropriate number of threads". Highest quality (lossless) is -crf 0.
    – llogan
    Commented Oct 4, 2016 at 18:16
  • Ok, that makes sense. I thought -crf 1 was the highest quality. I'll need to change that.
    – jrkt
    Commented Oct 4, 2016 at 18:24
  • If you do not need true lossless, with the giant files it produces, you can use -crf 18 or so which is roughly "visually lossless". See FFmpeg Wiki: H.264.

  • I eliminated [3:v]scale=1280x720,trim=duration=15[over0] because you can set size and duration (and frame rate) in the color source filter itself.

  • I removed -s 1280x720 -aspect 16:9 because your inputs are already 1280x720 and 16:9 display aspect ratio. I also removed -r 30 because it seems unecessary to change from 25 to 30 frames per second and would result in duplicated frames.

  • You don't need to declare pix_fmts in the format filter.

  • Added a -loop to watermark.png.

  • That's working to apply the watermark at the same time as the concatenation but the blend between the videos is gone. It just fades to black between the videos. Also, I have one other video I need to add to the command "vid-4.mp4" so it is 4 videos now. "vid-4.mp4" is the exact same format and length as the others.

  • @JonStevens I'm guessing all of these questions are related to your business. Nothing wrong with that, but have you considered hiring a consultant? See FFmpeg: Hire Developers or see my profile. As of now there are too many other questions in my FFmpeg volunteer answer queue.
